Williams Comfort Products QZO60A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZO60A is an open-end torque wrench head designed for precision fastening in heavy-duty service applications. Built to accept a Z-type shank measuring 0.990 inches, this head delivers a maximum torque capacity of 480 ft-lb, making it suitable for large fasteners that demand controlled, high-torque output. The 1 7/8-inch open-end configuration allows the head to engage fasteners in tight or offset positions where a standard torque wrench cannot reach. It is typically installed by mechanical technicians, millwrights, and trade professionals working on industrial equipment, heavy HVAC systems, or large mechanical assemblies requiring precise torque application.

This torque wrench head is used in situations where space constraints or fastener orientation prevent direct access with a conventional torque wrench. The open-end design allows engagement from the side of the fastener, and the Z-type shank interfaces with compatible torque wrench handles. The center measurement from the fastener to the retaining pin is 5 3/4 inches, a critical dimension when calculating true torque output with an offset head. It is sold as an individual unit and suits SAE fastening specifications.

Key Features

• 1 7/8-inch open-end head size for large SAE fasteners
• Maximum torque rating of 480 ft-lb for heavy-duty fastening
• Z-type shank with 0.990-inch shank size for compatible torque wrench handles
• Center of fastener to retaining pin dimension of 5 3/4 inches for accurate offset torque calculation
• Compact profile at 0.79 inches height for use in restricted spaces

Compatibility

Designed for use with torque wrench handles that accept a Z-type shank measuring 0.990 inches. Intended for SAE fastener applications requiring an open-end offset head configuration.

Installation Notes

This torque wrench head should be installed by qualified mechanical or trade professionals familiar with offset torque calculations. When using an offset head, always apply the appropriate correction factor to the wrench setting to account for the distance from the fastener center to the retaining pin. Verify the shank connection is fully seated and the retaining pin is secured before applying torque. Do not exceed the rated maximum torque of 480 ft-lb.
